A little less than one and a half seconds.
No, the shadow of the moon is not always long enough to reach the Earth. During a solar eclipse, the moon's shadow on Earth is limited to a specific region where the alignment of the sun, moon, and Earth allows for the shadow to be cast on the Earth's surface.
Communication between Earth and the moon is possible using radio waves, but real-time conversations have a delay of about 1.3 seconds each way due to the distance. Additionally, astronauts on the moon can communicate with each other using radio technology.
It takes around 3 days for a rocket to reach the moon from Earth.
It takes about 3 days for a lunar module to reach the moon from Earth.
The time it takes for a radio signal to travel from Earth to the moon and back can be calculated using the formula: Time = Distance / Speed of Light. The speed of light is about 299,792 kilometers per second. So, Time = (382,000,000 * 2) / 299,792 = 508.8 seconds. Therefore, it takes approximately 508.8 seconds for a radio signal to reach the moon and return to Earth.
The moon does not block radio signals sent from Earth, but it can cause disruptions in the signals due to its influence on the Earth's ionosphere. Radio waves can still reach the moon and be reflected back to Earth. NASA and other organizations have successfully sent signals to spacecraft on the moon and beyond.
No it can not be heard on earth because for a scream to travel as sound waves air is required and there is no air on the moon or between the earth and the moon. However if you were in a space suit with a working radio and screamed on the moon, that could be heard on earth because radio waves do not need air to travel in.
There is no air and sound waves do not propagate through vacuum.
Through the electromagnetic spectrum, specifically radio waves.
Radio waves can travel 300,000km per second. If someone was dialing from the moon to the earth, a signal would arrive in about 1.3seconds. The distance from the moon to the earth is 390,000km.
Transmission lag to the moon at lightspeed (the speed at which radio waves travel) is less than a second and a half (round trip is about 2.5 seconds), which is long enough to definitely be noticeable, but not really a major problem.

The normal time for a landing craft to reach the moon is approximately 3 days from time of launch.
